What does the formula TS = PS - (CS) calculate in moving (Target Slower) mode?

Closing Speed
Target Speed
Separation Speed
Patrol Speed

The correct answer is: Target Speed

The formula TS = PS - (CS) is used to calculate the Target Speed in moving (Target Slower) mode. In this context, TS represents the speed of the target, PS stands for Patrol Speed, and CS denotes Closing Speed. In scenarios where a moving observer, such as a law enforcement officer using radar, is tracking a target vehicle that is moving slower than the observer's vehicle, it is essential to determine the target’s speed. By subtracting the closing speed from the patrol speed, we can isolate the speed at which the target vehicle is moving. This calculation helps provide an accurate reading of how fast the target vehicle is traveling in relation to the moving observer. Understanding this formula is crucial for accurately assessing traffic speeds and ensuring enforcement activities align with legal speed limits. In moving mode, the radar system effectively utilizes this equation to present a more realistic view of the target’s speed compared to the observer's own speed, which is vital for enforcement accuracy.
